Uniform and remains constant for both the regions

2. 

A linearly increasing function of distance up to the boundary of the wire and then linearly decreasing for the outside region

3. 

A linearly increasing function of distance $r$ up to the boundary of the wire and then decreasing one with $\frac{1}{r}$ dependence for the outside region

4. 

A linearly decreasing function of distance up to the boundary of the wire and then a linearly increasing one for the outside region
